The research reported here was done using an earlier version of the satellite microwave sounding unit dataset. (co2coalition.org)
In addition to surface measurements over the world's land and oceans, satellite microwave sounding units have been providing estimates of global lower atmospheric temperatures since 1979. (carbonbrief.org)
As part of an ongoing joint project between UAH, NOAA and NASA, Christy and Dr. Roy Spencer, an ESSC principal scientist, use data gathered by advanced microwave sounding units on NOAA and NASA satellites to get accurate temperature readings for almost all regions of the Earth. (sciencedaily.com)
